A simple one-step process that produces both n-type and p-type doping of large-area graphene surfaces could facilitate use of the promising material for future electronic devices. The doping technique ...

The carrier concentration and conductivity in p-type monovalent copper semiconductors can be significantly enhanced by adding alkali metal impurities. Doping with isovalent and larger-sized alkali ...

The feature size of silicon-based transistors is approaching the theoretical limit, which puts forward higher requirements for the “atomic level manufacturing” of semiconductors. The basic idea of ...

French scientists have studied the fabrication of silicon heterojunction cells with p-type wafers. With the adoption of gallium doping, the p-type products could come close to matching the performance ...

Doping in semiconductors is adding a small amount of impurities into a very pure semiconductor material. It might sound strange to add impurities on purpose, but this is a critical to make ...

(Nanowerk News) The carrier concentration and conductivity in p-type monovalent copper semiconductors can be significantly enhanced by adding alkali metal impurities, as shown recently by Tokyo Tech ...
